The vacuum steam heat controller (JC-VSH) is designed for steam boiler or district steam heated buildings that use vacuum steam systems. A single controller is capable of controlling up to 12 zone valves.
True Dual two-stage heaters are available in both straight and U-tube versions with input ratings from 85,000/65,000 Btuh (high-heat/low-heat) to 200,000/145,000 Btuh for both natural gas and propane.
The IntelliCon® fuel economizer line for commercial forced air heating systems is designed to cut fuel consumption, reduce maintenance, and extend furnace life.
The SMVector drive has a power range up to 25 hp and features four modes of operation: V/Hz, enhanced V/Hz, vector speed, and torque. Other features include high starting torque, auto-tuning, advanced low-speed control, and dynamic speed regulation.
The VFDC-4000 mircoprocessor-based controller is designed for constant pressure applications using VFDs. Features include PID control, automatic alteration, datalogging, and communication capabilities.
The UNO-2170 PC-based controller supports PC/104 expansion, four serial ports, two Ethernet ports, and two USB ports. Features include a fanless Celeron CPU, backup SRAM, and an LM sensor which can retrieve CPU and core temperature for monitoring purposes.
The SMVector drive features a power range of up to 20 hp and four modes of operation: V/Hz, enhanced V/Hz, vector speed, and torque. The unit's input voltage ranges from 120 VAC one-phase to 600 VAC three-phase.
The MS-9050UD addressable control panel combines the capabilities of a fire alarm control panel and digital alarm communicator/transmitter into one circuit board.
The F220 Series of fire detectors features ChamberMaid™, which enables fast cleaning of the detector chamber; and Chamber Check®, a self-diagnostic system that visually alerts users is the detector's calibration is out of the factory-listed range.
